The subjective visual vertical (SVV) indicates perceived direction of gravity. Even in healthy human subjects, roll-angle dependent misestimations - roll over-compensation (A-effect, head-roll>60°&<135°) and under-compensation (E-effect, head-roll<60°) - occur. Previously, we demonstrated that, after prolonged roll-tilt, SVV estimates when upright are biased towards the preceding roll position, which indicates that ...

Hearing screening has been proposed to promote help-seeking and rehabilitation in adults with hearing impairment. However, some longitudinal studies point to low help-seeking and subsequent rehabilitation after a failed hearing screening (positive screening result). Some barriers to help-seeking and rehabilitation could be intrinsic to the profiles and needs of people ...

Abstract Many species are currently experiencing anthropogenically driven environmental changes. Among these changes, increasing noise levels are specifically a problem for species using acoustic signals (i.e., species relying on signals that use the same sensory modality as anthropogenic noise). Yet many species use other sensory modalities, such as visual and ...

Because immunoglobulin abnormalities may affect the kidney, investigation of renal biopsies requires immunohistological study of light chains. A problem is that most antibodies to light chains react with whole immunoglobulins as well as free light chains, and there are generally many more whole immunoglobulins than free light chains. The usefulness ...
